What plants do you absolutely have to have this Spring?

leslie6riFebruary 2, 2012

Hi all,

Now that Bluestone has raised its prices, and I've ordered two Camellias ('Winter's Rose' and 'April Remembered'--Bill reminded me how much I wanted them), I've decided to be picky about what I add to my gardens this year.

Corylopsis pauciflora is one necessity since my husband ever so carefully mowed down (by mistake) the adorable little one that I bought from Forest Farm years ago. --He thought it was a weed. Sigh. I still grieve for that little shrub.

A bunch of Hellebores thanks to the enablers here. 'Cinnamon Snow', 'Pink Frost', H. x ballardiae 'Spring Party', 'Regal Ruffles' --in red, in case they come in different colors, and 'Mellow Yellow', as well as another H. niger to keep my H. 'Joshua' company.

Dicentra scandens. A yellow climbing, possibly fragrant?, bleeding heart! Don't know if it will be hardy in Zone 6, but I'll plant it near the house and hope for the best.

A fairy rose because someone here (nhbabs?) reminded me how much I love it. I used to have one in my old garden.

An Illicium floridanum of some kind. There are new cultivars so I'll have to look into it.

Adiantum x mairisii --Hardy maidenhair fern. Hardy! Love those filigreed leaves and never thought I could get one that would be hardy in my garden.

I bought both the stachys & the Provence lavender on their half-price sale last spring and was so impressed I decided to order more whenever they have a sale. The lavender grew to nearly 12" tall before our so-called winter arrived and is still both beautiful & fragrant.

I'm toying with the idea of using the stachys along the curved edges of my full sun perennial bed. There's a local nursery where I can buy nice-size plants in quart pots for $4.99 in late May. I bought only one last year and have been kicking myself that I didn't buy more ever since. It grew into a gorgeous accent plant which is not why I bought it! My granite garden bench sits in the center of the bed & has a 12 ft. wide granite patio in front of it. I think the lamb's ear would add a softness to the granite. Am also experimenting with the idea of alternating the stachys [silver] and 'Bonfire' euphorbia [purple].

I was at New England Grows today and Tony Avent (of Plants Delight nursery) gave a talk on 100 must-have perennials. I had his plant list in hand and ticked off about a dozen plants, including Echinacea 'Solar Flare', Arisaema urashima (a cobra lily), Adiantum venustum (another hardy Maidenhair fern), and Ligularia japonica 'Chinese Dragon'.

Lots of projects this year, so maybe I'll get a handle on my plant acquisition compulsion at last.

We have a few projects this year, but also a very busy schedule, so not sure how many of them we will get to. We've been adding plants steadily for the past 6 years and I'm still trying to find the perfect spot for some of them. So my focus this year is to work on using the plant material I already have as effectively as possible. So more moving around. I'd also like to spend time dividing and increasing some of my favorite plants. I am even skipping Winter Sowing, which I've done every year except one.

Still....I keep a running list of plants I might like to have, but this year I just don't have to have them. I have enough perennials, but here's three that I would still like to have...

I'm a bit worried about Tony Avent's plant hardiness info on the Plant Delights website. I've seen both Dicentra scandens and Adiantum x mairisii listed as only hardy to Zone 7, though Tony Avent says Zone 6. But I'm hoping he knows.

I'd love more Arisaema, only have triphyllum. And have been looking at Amsonia. I've got 'Blue Sky' in my wish list at Plant Delights, but I'll look up 'Spring Sky'. And I'd love another lavender variety or two. I'm still working on part-shade beds, but hope to get around to a full sun bed this coming gardening season. It will open up a whole world of choices.

Leslie,
I was searching Dicentra scndens. Nice vine and blooms in light shade which is always a plus! Anyway, some growers listed it's hardiness as zone 5, 6 or 7. I'd say most had it as zone 6. There's only one way to find out if it will grow in your garden though! I don't think they're very expensive, and although we hate to see any plant die, I think this one would be worth trying.

I agree that it's worth being skeptical when a vendor gives a hardiness zone that seems too optimistic. He did mention in his talk that they trial their plants in ... Minnesota? Wisconsin? It was one of those horribly cold places, can't recall which.

I ran into a description of a tall, fast-growing holly that I'm considering now. It's Ilex attenuata 'Alagold', and was in an article on the Avant gardens blog, Garden Foreplay.

Does anyone grow this plant? It doesn't seem to be very widely available, but I might consider ordering it (though the plants would be small).

I bought an Ismene last year - which I really loved. It was only in bloom for about a week, and I decided then that that would be the end of Ismenes. BUT - I keep thinking about how stunning it was. And at this point I'm lusting for more. I did have to lift the bulb for the winter. But it wasn't that bad - I did it and it's marked in it's own little brown paper bag waiting for replanting.

Since bulb lifting wasn't that bad, I may try an agapanthus this year.

I have two ismene growing in pots since last year. They were started indoors last spring, then set outside for the summer and brought inside again last fall. They are growing......a little leggy even in full sun in my sun room, but they never bloomed. I'm thinking I'll withhold water now, let them die off, and replant in spring in the ground. I also have a big pot of Agapanthus that I grew in the ground for the first 5 or 6 years. It grew like a weed but never flowered so I stuffed it into a pot. Last year was its second year in a pot, which it filled completely, and it finally produced two flowers. I think they like to be crowded. Since it's in a pot, I do take it indoors in winter, in the cool back entryway and I only water it minimally to keep it from drying out completely. If you have a protected spot, you might give one of the hardy varieties a try.

I took a look at photos of Amsonia c. 'Spring Sky' and it looks almost white. I really like pale blue flowers (I have a Polemonium that is a lovely very light blue) so maybe... And it has larger flowers as well.

Bill, I'm definitely going to try Dicentra scandens. I can't resist. It will be planted in a raised bed near the house foundation --probably one of the warmest sites. If it doesn't come back I may even grow it as an annual. I like it that much (in theory, anyway). I think it may even attract hummingbirds.

diggingthedirt,

Minnesota/Wisconsin is good enough for me! Here's hoping they'll be as hardy as Avent says.

I'd love a red berried holly, but there are too many to choose from. That would take some research.

pixielou,

The Ismene is beautiful. Is it fragrant?

I've always wanted an Agapanthus. Isn't there a hardy Agapanthus --hardy to Zone 6? Bill, you grew your Agapanthus in the ground, yes? This may be a ridiculous idea, but if they need to be pot-bound to bloom, could one bury the pot?

Ann, I suppose you could bury a softer plastic pot. Obviously and clay or ceramic would be a goner! The only other thing I can think of would be some sort of large construction concrete piece, such as a cinder block that has the one large opening. It could be totally buried since only the roots need to be contained, so it wouldn't be an eyesore. That would survive the ground freezing. The only other thing that comes to mind is one of those concrete pipe sections, but they are generally pretty big around, so it sort of negates the "crowding" effect of being rootbound. I enjoy it in the pot though, and it's no problem to take in in winter.
I'm hoping that it blooms well this year.

Hi Steve - I've been googling it, and I see they have it at Woodlanders, and at some other (mostly southern) nurseries.

Sometimes I'll have a plant like this on my wish list for years, and then it just appears in the most unlikely place. That happened with I. pedunculosa, the longstalk holly; I found 4 or 5 nice-sized ones in the marked-down section of a local nursery (now defunct). I'd already decided that the mail order sources were too expensive for the tiny plants they were offering. Viola - instant hedge.

I'm thinking I'll call Sylvan Nursery in early spring, and see if they're going to stock it. Or maybe Avant Gardens, since they're responsible for this new obsession.

Claire have you had luck with the hardy begonias? I had one for about three years. The first season it was very nice. The second year it took forever to show above ground and made very weak growth, and no flowers. The third year it started out very late and very weak, and was dead even before fall frosts could have gotten to it.

Bill: I've never tried them; I'm just going by the reports that it's hardy to zone 6. What conditions did you plant it in? I'm planning to put them on the east side of the house where there's partial shade and I can easily water them. That's the viburnum spot too. Winds off the bay in the summer (but high up so not much salt) and protected in the winter.

The soil is sandy loam heavily amended with compost and I mulch generously.

I have had hardy begonias for a number of years and they slowly spread in my sandy soil and relatively shady location. They aren't splashy and don't compare in length of bloom to annual begonias, but seem to get by with no special care.
